The stomach deals with hydrochloric acid, this is acorrosive material and unless the body and stomach are protected from it death will be the result. Moving from the inside out. It is made up of five layers. First the mucosa layer, within this acid resistant layer stomach acid and digestive juices are produced. Next is the submucosa. This is in turn surrounded by the muscularis, a layer of muscle that moves and mixes the stomach contents. Then another two layers, the subserosa and the serosa, these are the outer layers of the stomach. Some times after eating or certain things the inner layers are penetrated, if this keep on happening it can lead to ulcers which if left untreated can be fatal.
The stomach contains mucous neck cells that make mucous to coat the epithelial cells lining the stomach. Without the mucous, the acidity and pepsin in the stomach would break down the lining of the stomach and create ulcers.
Protein digestion occurs in stomach only because it is safe for the body, as stomach has mucous secretions which prevents self digestion of stomach muscles by PEPSIN (enzyme for protein digestion) :)
Self-digestion of the stomach and small intestine is prevented by the mucus lining that protects these organs from the acidic and enzymatic activity of the digestive juices. Additionally, the cells of the stomach and small intestine have tight junctions that prevent digestive enzymes from leaking out and causing harm. The presence of bicarbonate in the mucus also helps to neutralize any excess acid that may come into contact with the lining.
the digestion of proteins begin in the stomach.
The muscle between the esophagus and stomach, called the lower esophageal sphincter, helps control the flow of food and liquids into the stomach. It opens to allow food to enter the stomach and then closes to prevent stomach contents from flowing back up into the esophagus. This helps prevent acid reflux and aids in the digestion process by keeping food in the stomach where it can be broken down by stomach acids and enzymes.
Most nutrient digestion occurs in the stomach
Food becomes semisolid after digestion in stomach.
two organs where digestion occur are stomach and small intestine
The cells in the stomach have a protective layer to prevent self-digestion by the hydrochloric acid (HCl) they produce. This layer includes mucus secretions that help create a barrier between the acid and the cells. Additionally, the cells have mechanisms to regulate the acidity of the stomach environment to prevent damage.
Digestion of food
The cardia is the area of the stomach where the esophagus connects, acting as a valve to prevent reflux of stomach contents back into the esophagus. It plays a role in controlling the entry of food and liquids into the stomach for digestion.
